Summary:
Echolocating bats emit ultrasound pulses to localize and capture prey based on returning echoes. They collaborate flight dynamics and acoustic sensing for effective foraging. We propose a new mathematical model describing nonlinear dynamics of the flight and pulse directions of an echolocating bat that approaches two successive targets. Numerical simulation of the model shows that the model bat successfully captures both targets within a short-time interval without losing them from its sonar beam depending on the parameter values and initial conditions. Such relationship between the flight and acoustic sensing was also observed in the behavioral data of the wild bats.
